BOLT AFPARATUS FOR DOORS ANI) WINDOWS.

Application led February 21, 1922.

10 all whom t may concern:

Be it known that I, DANIEL W. BLACK- wnLL, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented a certain new and useful Bolt Apparatus for Doors and lVindows, of which the following is a specification.

My invention relates to bolt apparatus for securing and locking doors, windows and screens and the .objects of my invention are: First, to provide an apparatus of the class described which will securely hold the door, window or screen in a closed position; second, to provide an apparatus of the class described which is positive in action; third, to provide an apparatus of the class described 'which will'bolt the door, window or screen at both t'op and bottom thus securely bolting the same even though said door, window or screen may be distorted or warped; fourth, to provide means for releasing both bolts with one action; fifth, to provide an apparatus of the class described which is concealed in the stile yof said door, window or screen; sixth, to provide an apparatus of the class described which is novel'ly constructed and seventh, to provide an apparatus yof the class described which is simple and economical of construction, durable, easy to adjust and which will not readily deteriorate or get out of order. l

With these and other objects in view as will. appear hereinafter, my invention consists of certain novel features of construction, .combination and arrangement of ,parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters 'of reference thereon which form `a part of .this application, in which:

Figure 1 is a fragmentary front elevational view of a window showing the bolts 4of my apparatus projecting beyond the up- -per and lower' edges of said window; Fig. 2 is an edge view thereof, showing the exterior plates and strips covering or concealing the bolt operating apparatus; Fig. 8 is a Apartial sectional and partial elevational view of a Selal No. 538,279.

mentary sectional view taken through 5-5 of Fig. 4; Fig. y6 is ar fragmentary sectional view .taken through 6-6 of Fig. 4; Fig. 7 is a fragmentary frontelevatio-nal view, partly in section, of a .door showing amodiiied form yof my bolt apparatus. in position; Fig. 8 isy lar parts and portions throughout the several views of the drawings.

A The knob or handle 1, shank 2, plate 3, primary operatmg arm 4, secondary ,operating arm 5, ycasing `6, operating cables 7, clevis 8, bolt 9, spring 10, angle plate 11,` plate 12,.

and wire concealing vstrip 13 rconstitute the principal parts and portions of my structure. The knob or handle 1 is ysecuredto :the

-square shank Q'by meansof a screw 1a, lsaid shank projecting through a circular .opening 3 inthe plate 3 is allowed to .turn in said A:plate and retained in position therein` by the washer 2n and pin 2l. Said plate 3 is ysecured to the door, window `or screen stile by :the lscrews ,8b. YThe primary operating arm 4 is provided with a square socket 4a to receive `one end 'of said square shank 2. Said operating arm 4 is also provided with aprojections or teeth 4b to vengage .teeth 5bof1the secondaryoperating arm 5, which is pivotally mounted at '5a on the p-in 6C of the casing 6. The arms 4c and 5C .of the respective operating arms 4 .and 5 are provided withpa series of holes 4d and 5d equally spaced. The .extended yarms are notched r4on the edges between the various holes so that 4said arms may beconveniently lbrolen Aoff at any desired Ilength, said length varying with ythe r"location of the 4casing 6 with respect to the edge of the door, window, or screen-stile, said casing being preferably located in the center of the stile. The primary operating arm 4 is provided with Jbosses 4e and 4f which are pivotal-ly mounted in 6b of casi-ng G` and casing cover 6a.

Said casing is inserted a mortise in the face of the stile of the door provided for the same and secured to said stile by means of the screws 6d. To each operating arm at the end hole is attached a cablev7, which has attached to the other end thereof a clevis 8 which is loose-ly mounted on the reduced square portion 92L of the bolt 9 and retained thereon by the pin 9*. Said bolt is reciprocally mounted in the angle clip `11 and projects through an opening 112L of the clip 11 and conforms in shape to that of the outer portion of said bolt. The bolt is also secured in a transverse position at its reduced square portion by the clip 11b secured to clip 11. Mounted over the bolt 9 is a coil compression spring 10 interposed between the short leg of plate 11 and the clip 11b forcing the bolt in its outward position and therefore keeping the door, window, or screen closed. The operating arms L and 5 are concealed at the edge of the door stile by the plate 12 and the cable 7 are concealed by the U-shaped strip 13 as. shown best in Fig. 6 of the drawings. p

It is obvious, therefore, that by turning the knob or handle 1 in the counter clockwise direction as shown in Fig. 4L of the drawings, that the operating arms positively engaged, exert tension on the cables 7 therefore pulling the bolt 9 inwardly or disengaging the same from the door, window or screen sash, and compressing the spring 10.

1n the modified forms of construction shown in Fig. 7 to Fig. 13 of the drawings l have shown a positive tripping device for actuating the bolt. The tripper 14 as shown best in Fig. 11 of the drawings is pivotally mounted at 14a on pin 15 fixed to the angle clip 11. Said tripper is provided with an extended portion 14:1 which engages a slot l9C at'the outer portion of the bolt and is kept in engagement therewith by a spring 16, one end of which is fixed to the pin 15 and the other end of which is engaged with a raised portion 141:c on the tripper which also serves as a stop for the rod 17. Said rod is reciprocally mounted at its flattened end in theraised portion 11C of the clip 11 and is externally threaded at its other end adapted to be screwed into the plunger Said plunger is reciprocally mounted in the raised flanges of the clip 19 and is held in its outward `position by the coil spring 20 mounted on said plunger and interposed between ythe shoulder 18 of said plunger and the inner flange of the clip 19. The plunger 18'is provided with a stop 18b thus limiting its outward movement. Said plunger is also provided with a slot in its outer end to receive a screw driver `or other tool for adjusting the space between the rod 17 and the stop 14 of the tripperlt, thus fixing the tripping position to the position of the door relative to the sash.

It is obvious that as the door is closed the outer portion of the plunger 18 engages the inner face of the sash frame thus compressing the plunger' against the spring 2O and bringing the rod 17 in engagement with the stop 14C of the tripper 14 disengaging `the. extended tripper portion 14" from the slot 9c of the bolt 9, thus bolting the door. lt is further obvious that by turning the knob, as previously described, the bolt 9 is pulled within the door stile, the tripper 14 is forced by the tension of the spring 16 to engage saidV bolt 9 at the slot 9C, thus positively disengaging the bolt from the door.

Although l have shown and described a particular construction, combination and arrangement of parts and portions and certain modifications thereof I do not wish to be limited by this particular construction, combination and arrangement nor to the modifications, but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. An apparatus of the class described, including a closure member, bolt members reciprocally mounted in the ends of said closure member, wire links connected to said bolt members, variable length operating arms, positively engaged with each other and swivelly connected to the4 free ends of said wire links, and a knob pivotally mounted in the closure member operatively connected with one only of said operating arms.
